I've never used Woolies Mobile, but I think $29 off a $30 starter pack is good value. $2 delivery for SIM packs, maximum 2 packs per order.
Bonus: new activations before 30 June get 6GB data (normally 2GB + current bonus 1GB) — details here
According to their Coverage page Woolies "uses parts of Telstra's 4G and 3G mobile networks".
Finishes 31 May, thanks @Sydney and @Obey

6. Learning that I missed a lot of useful details!
The starter pack has to be activated within 3 months of purchase. thanks Sydney11
12 Gb of data is still available for $33.50 at Woolies (stores)- no bargain compared to this deal but amazing on Telstras network.
